There are only 2 ways to put money into a Roth IRA: (1) an annual contribution, which must be based on earned income and can only be made up to a set dollar amount annually; and (2) a conversion from a traditional IRA, which requires immediate income recognition of the converted amount (assuming the account was funded entirely with deductible contributions). Amounts that must be taken as required minimum distributions (RMDs) are not eligible for conversion. Only amounts exceeding the RMD can be converted.
Increase in value of property due to market conditions. When you sell appreciated property, you pay tax on the appreciation since the date of purchase. When you donate appreciated property held long term, you may generally deduct the appreciated value.
